Abstract The long-debated issue of the coronal abundances in active stars has not yetarrived to conclusive results, in large part because for most of the stars forwhich coronal abundances have been determined, no published photosphericabundances are available. This is specially true for the most active stars, inwhich large rotational velocity complicates the measurement of photosphericabundances. We propose to determine the coronal abundances of a sample of activestars with low projected rotational velocities, for which we have determinedaccurate photospheric abundances.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
